TRIPOD.

To all whom it may con cern;

Be it known that l, HANs Jns CHRISTIAN J ESSEN, a citizen of the United States, and a resident of Nevada, in the county of Story and State of Iowa, have invented a new and Im roved Tripod, of which the following is a ful clear, and exact description.

- The object of the invention is to provide a new and improved tripod for supporting cameras, telescopes, transits, gun-rests, etc., and arranged to permit of firmly setting the tripod on uneven ground or rocks, to allow convenient adjustment of the members of the tripod to bring the article to be supported into the desired position, and to permit of folding the tripod into a comparatively small space for carrying it from place to lace.

The invention consists of nove features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding'parts in all the views.

Figure 1 is a side elevation oft-he improvemerit, set up and shown asis Tiipportinga cam era; Fig. 2 IS a side-elevation of-the im rovevment partly folded up; Fig.7 3 is an en a'rgedc lan view of the improvement, the camera eing removed; Fig. 4 is a sectional view on the line 44 of Fig. 1 Fig. 5 is a transverse section of the improvement on the line 55 of Fig. 4 Fig. 6 is an enlarged sectional plan view of the bottom brace for the legs; and Fig. 7 is a reduced plan view of the same.

The main leg A. and the two auxiliary legs B, B arepreferably made tubular, and are provided at their lower ends with telescoping points C, adapted to be fastened in place in the legs by set screws D, as plainly indicated in Figs. 1 and 2. The legs A, B and B are connected with each other by a bottom brace E formed of a tubular rod E pivotally connected at one end to a sleeve t mounted to slide on the main leg A and adapted to be secured thereto-by a set screw E In the free end of the tube E is mounted to slide a rod'E adapted to be fastened in place by a set screw E and on the said rod E5 are pivoted the rods E", E7, pivoted to sleeves E held on the lower ends of the auxiliary legs B and B. Now b the arrangement described, the sleeve 5, on loosening the set screw E, can be moved up on the leg A, to allow of folding Specification of Letters Patent.

the legs B and B towards the leg A, as indi cated in Fig. 2, the rods E, E with the rod E being free to slide in the tube E on loosening the set screw E Inv order to lock the rods E, E when. spreadin any desired point, locking links E are provided, see Fi 7, and fulcrumed on the rods E E and iastened together b a clamping screw E.

. An arm is connected by a hinge G to the upper end of the main leg A, and the under side of this arm F is connected by a brace H,

with asleeve H, mounted to slide on the In the sides of the arm F are formed longi t-udinally-extending guideways F- (see Figs. 1., 2, 4 and 5), enga ed by clamping screws 1, pivotally' enga ed y the upper ends of the auxiliary legs and B, to permit of adjust ing the said up er ends of the legs B and B lengthwise on til of the ground on which the tripod is to be mounted.

in the upper end of the main is A tele scopes a rod J, adapted to be fastener in place by a set-screw J, and on the upper end of the said rod J is pivoted at K a quadrant K, attached to and forming part of a table L, the u'adrant-K being provided wit a segmental s 0t K engaged by a clamping screw K held on the rod J, to fasten the quadrant K and consequently the table L in any desired posi tion.

The table 'L is provided with a lemthwise extending slot L, engaged by a clamping screw N, passing through a platform 1 and screwing into a nut on the camera 0 or other article to be supported, the camera resting On loosening the set screw e arm F, to suit the condition table L is swung downward and the rod J is telcscoped in the le A, and the auxiliary legs B, B are folded up, as previously mentioned and shown in Fig. 2, by loosening the clamping screws I and the set screws E E to swing the arm F downwan and the brace E upward, as indicated in said Fig. 2. By the arrangement described the tri od can be folded into a comparatively small space for conveniently carrying the t1 'po l from place with an adjustable telescoping extension at its upper end, a table pivoted on the said extension, and means for securing the table in adjusted position.

2. A tripod having connected legs, of which one is provided with an adjustable telescoping extension, 8. table pivoted onthe said extension and having a quadrant, and a clam ing screw on the said extension engaging the said quadrant.

A tripod having connected legs, of which one is provided with an adjustable telescoping extension, a table pivoted on the said extension and provided with an elongated slot, a support held adjustably on the said table and provided with a clamping screw engaging the said slot, and means for securing the table in place on the extension.

4. A tripod comprising a main leg and auxiliary legs, an arm hinged on. the said main .leg and slidably engaged by the auxiliary legs, and a bottom brace connecting the legs with each other.

5. A tripod comprising a main leg and auxs iliary legs. an .arm hinged on'the said main leg and slidably engaged by the auxiliar legs, an arm brace pivotally connected wit the said arm, a collar slidably secured on the said main leg and pivotally connected with the said arm brace, and a bottom brace connecting the legs with each other.

6. A tripod comprising a main leg and auxiliary legs, an arm hinged on the said main leg and slidably engaged by the auxiliary legs, an arm brace pivotally connected with the said arm, a collar slidably secured on the said main leg and pivotally connected with the said arm brace, a bottom brace connecting the legs with each other, the said bottom brace comprising a sleeve adjustably held on the main leg, a tube pivoted with the said sleeve, branch rods pivotally connected with the said auxiliary legs, and a shank secured in the free end of thesaid tube and pivotally connected with the said rods.

7. A tripod having a main leg and auxiliary legs connected at their tops, an arm hinged on the main leg and slidably engaged by the auxiliary legs, said main leg being provided with an adjustable telescoping cxtension at its upper end, and a table adjustably mounted on the extension.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
